Open PuTTY to telnet into multiple devices using Python
Introduction
The article explains and provide python script to open Putty terminal and telnet to multiple devices in a single click.
Prerequisites
Basic Knowledge on Python scripting and installing modules.
Lets Start !
1. Install module 'pywinauto'.
Module 'pywinauto' is a predefined library to open system applications.
- Open python folder:
- Write CMD in the path and enter:
- Install module 'pywinauto' using CMD:
C:\Users\pashukl2\AppData\Local\Programs\Python\Python39\Scripts>pip
install pywinauto
2. Create an excel file and save it as .csv
3. Python Script:
Import Modules.
'pywinauto.application' module is used for opening an existing application on the system.
'time' module for adding sleep time when pushing data to telnet sessions.
'csv' module for opening and reading CSV files.
from
pywinauto.application import Application
import time
import csv
Convert CSV file into Dictionary and storing network device credentials into variables called as x,y,z and w.
dictionary = {}
with open(r"C:\Users\pashukl2\Desktop\Telnet1.csv") as f1:
csv_file = csv.DictReader(f1)
for row in csv_file:
dictionary = dict(row)
print(dictionary)
x = dictionary["IP"]
y = dictionary["Username"]
z = dictionary["Password"]
w = dictionary["Enable Password"]
Following code will open PuTTY application, telnet to IP address and will start inserting credentials automatically.
app = Application().Start(cmd_line=u'putty telnet@'f"{x}")
putty = app.PuTTY
time.sleep (1)
putty.TypeKeys (y)
putty.TypeKeys ("{ENTER}")
time.sleep (1)
putty.TypeKeys (z)
putty.TypeKeys ("{ENTER}")
time.sleep (1)
putty.TypeKeys ("en")
putty.TypeKeys ("{ENTER}")
putty.TypeKeys (w)
putty.TypeKeys ("{ENTER}")
4. Complete Python Code
import time
from pywinauto.application import Application
import csv
dictionary = {}
with open(r"C:\Users\pashukl2\Desktop\Telnet1.csv") as f1:
csv_file = csv.DictReader(f1)
for row in csv_file:
dictionary = dict(row)
print(dictionary)
x = dictionary["IP"]
y = dictionary["Username"]
z = dictionary["Password"]
w = dictionary["Enable Password"]
app = Application().Start(cmd_line=u'putty telnet@'f"{x}")
putty = app.PuTTY
time.sleep (1)
putty.TypeKeys (y)
putty.TypeKeys ("{ENTER}")
time.sleep (1)
putty.TypeKeys (z)
putty.TypeKeys ("{ENTER}")
time.sleep (1)
putty.TypeKeys ("en")
putty.TypeKeys ("{ENTER}")
putty.TypeKeys (w)
putty.TypeKeys ("{ENTER}")
5. Run the script
